Campus Mailing Lists, Calendar Events

The Campus Mailing List server does not impose restrictions on attachment types. However,
there is a maximum 10MB total message size limit. Keep in mind this
setting defines the total "message size" which represents the message
header (to/from, etc), the body(message) and any attachments. All
attachments are translated to MIME which can more than double the size
of a binary file. For example, the MIME conversion of a 5MB jpg becomes
a +10MB MIME-attachment which exceeds the max message size. To
work-around the 10MB limit subscribers can:

Reduce
the size of their attached files to something that is more compatible
with MIME. A total attachments around 4MB should be safe but each binary
format expands into different MIME sizes.

Use the "Shared Documents" directory that is associated with the mail list. The link , shared documents, is located in the left column of the mail list's web interface.

Calendar Event Attachments

Many
customers have noticed calendar events behave differently from other
attachments. The Campus Mailing List Server is simply passing the
attachment as any other attachments and does not manipulate the data or
rename the file. However, each email client (Outlook, GMail, Yahoo,
Hotmail, etc..) independently defines how they choose to handle the
calendar event. We've notice different behaviors when you "create a calendar event" and invite a list to the event vs. "drag-n-dropping a calendar event" to an email and send it to a list.

In summary, there are a few options for sending calendar events to a mail list:

Option 1)
Best: To make sure your invite makes it to "all" the subscribers on
your list, regardless of which email client they use, we recommend you
add the event information to the body of the message. This will ensure
your subscribers receive the relevant information and they can create
the appropriate event on their calendar. + option 2 for those user's
whose email client will provide the add to calendar options.

Option 2) Add
the mail list address to the invitee list for the event and most email
clients will allow the user to interact with the data. Most email
clients not all....

Option 3)
Worse: drag-n-drop a calendar event to an email that you're sending to
a mail list. In this case, most email clients see the attachment as
suspect and will rename it, delete it or provide an ascii version of the
information in a text file.
